The issue

We have tried playing videos with Alpha on the Composition Layers, using both packing modes (Top Bottom and Left Right), and both with BGRA and OES texture formats, none of them had a working alpha effect.
On all the cases only the Stereo effect works, while the alpha packed part of the frame just plays in grayscale.
Is there support for alpha playback on Composition Layers or it hasn't been implemented yet?

Have you tried following the advice in this thread?

Packed alpha is not currently supported with XR Composition Layers.

We should be able to get this to work with BGRA texture output mode, however until such a time as OpenXR adds support for packed alpha it will not work with OES mode.

Marking this as an enhancement for now.
